-----------------------------------------
Hi Ben, nice to hear that. Just to be sure: https://reviews.apache.org/r/46892/
- this is the RB issue.
I wanted to try one last help according to the things mentioned in the RB, but
yesterday I pulled the mesos sources, compiled and I'm unable to run mesos
1.0.0 with marathon 1.1.1 as I keep getting "Mesos JAR version 0.28.0 is not
backwards compatible with Mesos native library version 1.0.0".
So I guess now its up to you. The solution is pointed out on my github, maybe
you just need to make it a bit nicer :)

> Key: MESOS-4279
> URL: https://issues.apache.org/jira/browse/MESOS-4279
> Project: Mesos
> Issue Type: Bug
> Components: containerization, docker
> Affects Versions: 0.25.0, 0.26.0, 0.27.2, 0.28.1
> Reporter: Martin Bydzovsky
> Assignee: Benjamin Mahler
> Priority: Critical
> Labels: docker, mesosphere
> Fix For: 1.0.0

> I'm implementing a graceful restarts of our mesos-marathon-docker setup and I
> came to a following issue:
> (it was already discussed on
> https://github.com/mesosphere/marathon/issues/2876 and guys form mesosphere
> got to a point that its probably a docker containerizer problem...)
> To sum it up:
> When i deploy simple python script to all mesos-slaves:
> {code}
> #!/usr/bin/python
> from time import sleep
> import signal
> import sys
> import datetime
> def sigterm_handler(_signo, _stack_frame):
> print "got %i" % _signo
> print datetime.datetime.now().time()
> sys.stdout.flush()
> sleep(2)
> print datetime.datetime.now().time()
> print "ending"
> sys.stdout.flush()
> sys.exit(0)
> signal.signal(signal.SIGTERM, sigterm_handler)
> signal.signal(signal.SIGINT, sigterm_handler)
> try:
> print "Hello"
> i = 0
> while True:
> i += 1
> print datetime.datetime.now().time()
> print "Iteration #%i" % i
> sys.stdout.flush()
> sleep(1)
> finally:
> print "Goodbye"
> {code}
> and I run it through Marathon like
> {code:javascript}
> data = {
> args: ["/tmp/script.py"],
> instances: 1,
> cpus: 0.1,
> mem: 256,
> id: "marathon-test-api"
> }
> {code}
> During the app restart I get expected result - the task receives sigterm and
> dies peacefully (during my script-specified 2 seconds period)
> But when i wrap this python script in a docker:
> {code}
> FROM node:4.2
> RUN mkdir /app
> ADD . /app
> WORKDIR /app
> ENTRYPOINT []
> {code}
> and run appropriate application by Marathon:
> {code:javascript}
> data = {
> args: ["./script.py"],
> container: {
> type: "DOCKER",
> docker: {
> image: "bydga/marathon-test-api"
> },
> forcePullImage: yes
> },
> cpus: 0.1,
> mem: 256,
> instances: 1,
> id: "marathon-test-api"
> }
> {code}
> The task during restart (issued from marathon) dies immediately without
> having a chance to do any cleanup.
